Patented May 20, 1930 UNITED STATES WALTER R. SCHLAGE. OF SAN FRANCISCO,CALIFORNIA, ASSIGNOR TO SCHLAGE LOCK PATENT OFFICE CO., 01 SANFRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA LATCH-FACE-PLATEMOUNTING Application filed July 18,

This invention relates to door latches, such as shown in my co-pendingapplication entitled Door latch filed June 18, 1928, Serial Number286,078 and especially to improvements in the construction and assemblyof the latch housing and face plate cooperating therewith.

The object of the present. invention is to generally improve andsimplify the construction and operation of door latches, and especiallyto provide a structure whereby the connection between the latch housingand the face plate is improved and strengthened, and whereby turningmovement of the latch housing with relation tothc face plate isprevented.

The fact plate and latch housing assembly is shown by way ofillustration in the accompal'iying drawings, in which:

Fig. 1 is a perspective view of the latch housing and face plate, asassembled,

Fig. 2 is a similar view looking from the face plate side,

Fig. 3 is a perspective view of the auxiliary face plate.

Fig. 4 is a perspective view of the latch housing,

Fig. 5 is a longitudinal vertical section of the latch housing and faceplate, when assembled.

Referring to the drawings and particularly Figs. 2, 3 and 4, A indicatesa main face plate, B an auxiliary face plate, and C the latch housing.The main face plate may be constructed of any suitable metal, it isrectangular in shape, as shown, and it is provided with a central 0)ening 2 through which the latch extends and whereby the latch isguided. The main face plate is otherwise provided with two openings,such as indicated at 3, 3 for the reception of screws whereby thefaceplate may be secured to the edge of a door. The openings 3 arepreferably formed by punch or press operation, so as to force the metaloutwardly through the rear face of the plate,

thereby forming an annular shoulder 4, which i is later on seamed overto secure the auxiliary face plate B, as will hereinafter be described.

The auxiliary face plate B is rectangular in shape, and of a sizesimilar to the main 1928. Serial No. 293,559.

plate A. It is usually constructed of a lighter material, and it isprovided with side flanges 5, and end flanges t3, 6. It is also providedwith a central opening 7, so as to permit it to he slipped over thelatch housing 0, and it is further provided with perforations 8, 8 atopposite ends, to permit fastening screws to extend therethrough. Thelatch housing (I is cylindrical and elongated in form. as shown in Figs.4 and 5. The inner end is provided with a suitably shaped opening 10, topermit the latch shank or plate to extend therethrough. The forward endis provided with an annular flange 11, and this is cut away on oppositesides, as indicated at 12. 12, to form flattened opposed surfaces whichare engaged by the side flanges I, 5 of the auxiliary face plate It. Thedistance which the flanges 5, 5 and (i. (5 project is equal or slightlyless than the thickness of the flange [1, so that a clamping action isexerted when the flange 11 is interposed between the. plates A and 15.

In actual operation the auxiliary. face plate Bis slipped over the latchhousing t". and this is turned so that the flattenedsides 12 of theflange 11 will lie between the side flanges 5. This is important as itlocks the latch housing against rotation. The main face plate A is thenplaced against the flange face of the auxiliary plate B, and the annularflange previously referred to will then extend through the screwopenings 8. The plates are then placed tightly together and the aunula'rflanges seamed over. as shown at H. in Fig. The flange 11 of the latchhousing thus securely clamped between the main face plate and theauxiliary plate, and it is fur thermore secured against rotation due tothe engagement of the side flanges 5, and the flattened face 12 of thelatch housing flange. The structure and connection is rigid, anddisplacement of the parts with relation to each other is positivelyprevented as the plates A and B are secured at opposite ends by theseamed annular flanges 4, and thelatch hous- I wish it understood thatvarious changes may be resorted to within the scope of the appendedclaims, similarly that the materials and finishes of the several partsemployed may be such as the manufacturer may decide, or varyingconditions or uses may demand.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. In a device of the character described, a latch housing having anannular flange formed at one end, a main face plate engaging the flangedend of the latch housing; and an auxiliary face plate secured to therear side of the main face plate and engaging and clamping the annularflange of the latch housing with relation to the main face plate.

2. In a device of the character described, a latch housing having anannular flange formed at one end, said flange being flattened onopposite sides; a main face plate engaging the flanged end of the latchhousing; an auxiliary face plate secured to the rear side of the mainface plate and engaging and clamping the annular flange of the latchhousing with relation to the main face plate; and means on the auxiliaryface plate engaging the flattened sides of the flange and securing thelatch housing against rotation with relation to the main and auxiliaryface plates.

In a (lcYh-e of the character described, a cylindrical shaped elongatedlatch housing, substantially closed at one end and open at the otherend: an annular flange on the open end of the housing; said flange beingflattened on opposite sides; a main face plate engaging the front faceof the flange; an auxiliary face plate having an opening formed thereinpermitting it to he slipped over the latch housing so as to engage therear face of the flange; and means whereby the face plates are rigidlysecured with relation to each other so as to elamp and secure the flangeof the latch housing.

4. In a device of the character described, a cylindrical shapedelongated latch housing, substantially closed at one end and open at theother end; an annular flange on the open end of the housing; said flangebeing flattened on opposite sides; a main face plate engaging the frontface of the flange; an auxiliary face plate having an opening formedtherein permitting it to beslipped over the latch housing so to engagethe rear face of the flange; means whereby the face plates are rigidlysecured with relation to each other so as tov clamp and secure theflange of the latch housing; a pair of side flanges on the auxihary faceplate, and means on the latch housing flange engageable with the sideflanges and securing the latch housing against rotation with relation tothe face plates.

5. In a device of the character described, an 7 elongated cylindricalhousing having an an nular flange formed at one end, and flattenedportions formed on opposite sides of the flange, an auxiliary faceplate, rectangular in shape and having side and end flanges formedthereon; said flanges projecting from the inner face of the plate adistance slightly less than the thickness of the flange on the latchhousing; said auxiliary face plate having a circular opening formedvtherein permitting it to be slipped over the latch housing so as toengage the rear face of'the latch housing flange, and to assume aposition where the side flanges of the auxiliary face plate will engagethe flattened portions of the latch housing flange so as to secure thelatch housing against rotation with relation to the auxiliary face plateand a main face plate secured to the auxiliary face plate, and clampingthe latch housing flange between the face plates.

6. In a device of the character described, a

face plate, an auxiliary face plate, said auxiliary face plate having anopening formed therein to receive one end of a latch housing,

removal.
